Chapter 9. Q & A
Q1. How can we use VHF exclusively? See page. 4-2.
When your own ID (MMSI) is not registered FM-8800S/D becomes the only operable VHF function. However, when you press [CALL], [DISTRESS] and [LOG] key(DSC related function keys), “NO MMSI” a pop-up window appears.
- Even if the position data are not inputted, it is not a problem.
- Even if position data is not inputted, “GPS ERROR” pop-up window will not appear.
In the FM-8800 program INTL VER. is 03.01 and after, and Russian Ver., the display of “GPS ERROR” changes to “EPFS ERROR”.
Q2. What are the differences between FM-8800D and FM-8800S?
See page. 5-4, 5-8, 8-19.
FM-8800D has FULL-DUPLEX function and FM-8800S has SEMI-DUPLEX function. FM-8800D with DUPLEX has DUPLEXER and DUP RX board installed in it. The main program is commonly used by both FM-8800D and FM-8800S.
Switching a program detects whether DUP RX board is installed or not and is carried out automatically.
Q3. Please tell me the priority of communication order. See page. 4-5.
Distress Alert of DSC has the highest priority. Priority order of a telephone is:
Transceiver unit > Remote-1 > Remote-2 > Remote-3 > Remote-4. Wing MIC is independent of other units and cannot be used while any of the other units are transmitting a signal. Also, when you are transmitting a signal from Wing MIC, other units cannot transmit a signal.
In the DISTRESS mode after transmitting the distress alert, the priority of the Transceiver unit and each Remote unit are equal.
Q4. Do the Transceiver unit and Remote Handset have to be installed in designated location? See page. 4-5, Q37.
Since the transceiver unit has a higher priority than a Remote Handset, install the Transceiver unit in ship’s W/H.
Q5. Receptible sentence. See page. 4-16.
IEC61162-1 (Corresponding to NMEA Ver.3):
GGA > RMC > GNS > GLL and ZDA.
Applicable talker name is:
GP > LC > DE > II > IN > EC > TR > LA > OM
When you are using GPS data, you cannot manually input position data.
Chapter 9. Q & A
Chapter 9. Q & A
Q6. Please tell me about the Alarm output. See page. 4-11.
When you receive Distress/Urgency DSC message, the alarm always goes off but when you receive Routine and Safety DSC message, you can set up ON/OFF by selecting [MENU] -> ALARM.
As for external alarm, it synchronously functions with alarm outputted from the Transceiver unit and Remote stations. Distress/Urgency alarm will continue to go off until you press [CANCEL] key. Safety and Routine alarm will automatically stop after 2 minutes or until you press [CANCEL] key.
Note; The EXT ALM circuit on CPU board is changed to the normal close from production in June 2006.
Q7. Can Carbon MIC be used in place Wing MIC? See page. 4-28.
Either Carbon MIC or Dynamic MIC can be used. However, setup with J5 on CPU board will be necessary.
- Carbon MIC: J5 -> Jumper between #2 and #3 - Dynamic MIC: J5 -> Jumper #1 and #2
Q8. Can Remote Handset be used alone without Transceiver Handset on?
See page. 4-29.
Yes it can although setup that keeps HOOK signal on the Transceiver unit side
“ON HOOK” at all time is necessary. You will then have to make a jumper connection between #1 and #2 on J15.
Q9. Does Remote Handset have to be wired in daisy chain?
See page. 4-26.
Communication between Remote station and Transceiver unit is carried out on the basis of ID number set up for each Remote Handset. Either daisy chain method or parallel wired connection from Junction Box etc, can be used. When connecting Remote stations, terminate data line of the electrically farthest Remote station.
Q10. Can VHF antenna be used together with CH70 WR antenna?
See page. 4-30.
It is operative. However, you cannot watch CH70 signal from continuously working CH70 board during a transmission. Connect it with a coaxial cable between J2 of CH70 RX board antenna inputting and J5 of TX/RX board. The coaxial cable is Mini-pin assembly (1) L-420. (Supplied material: Code 000-151-748)
Q11. Is a Junction Box: IF-8810 necessary?
For example, if you can connect GPS data inputted to Transceiver unit to [IEC-61162/REMOTE] port directly, IF-8810 is actually not necessary. However, it becomes necessary if you want to connect it to Remote stations.
Chapter 9. Q & A
Q12. How to adjust LCD contrast? See page. 1-4, 4-1.
Press [SHIFT] key and adjust by a channel knob or by pressing [▼] and [▲]
key. It is adjustable in 16 different levels of contrasts and a set up value can be stored even if the power is OFF/ON. As for the brightness of LCD, press SHIFT key and adjust it with [2] key.
Q13. How to cancel menu’s protection? See page. 4-1.
See FURUNO Information: FQ5-2005-015 for the password. Make a jumper connection between #2 and #15 pin of [PRINTER] port. Or, jumper connection between #25 and #26 of IF-8810.
Then, press [MENU] -> SYSTEM -> [ENT] key and input the password. (The same as FM-8500’s password: XXXXXX) After the protection is cancelled, you can go into all system menus to register/change MMSI, etc.
Q14. Please tell me what to check after installing. See Check List.
Setting to check after installation:
- The least you have to check is to set up MMSI by [MENU] -> SYSTEM -> MMSI
- When more than one Remote stations are installed, make sure of their ID number.
Turn on the power while pressing [MENU] key on the Remote Handset and then, enter ID number.
- Make sure that position data are inputted.
- Carry out DSC and voice communication test between No.1 VHF and No.2 VHF. When you have only one VHF installed, make sure of VHF TX output and carry out a test by going to [MENU] -> SYSTEM -> T/A to check the monitor sound outputted from CH70 RX board.
Q15. How do I adjust the frequency? See page. 6-3.
There is no part that adjusts it. Since Transceiver’s reference OSC uses TCXO, the stability of frequency is excellently maintained. If the frequency tolerance is more/less than ± 10 ppm (Approximately +1.5 kHz) as a rule, change CPU board which has TCXO.
Q16. How do I measure DSC tone frequency? See page. 6-5.
In the FM-8800 program, INTL Ver.-03.01 and after, also Russian Ver., tone selected from a speaker is outputted when performing the TONE TEST.
As for the FM-8800 program (Ver.02.03 and before);
There is no part that measures it. One of VHF monitors it.
- Setup on TX side
Set up by [MENU] -> SYSTEM -> TONE TEST -> MARK or select SPACE and PTT ON.
Chapter 9. Q & A
Q17. Will the Program-Ver. indication remain the same even after updating the program? See page. 7-10.
An indication shown by [MENU] -> PROGRAM VERSION will not change.
When confirming a detailed program version, select [MENU] -> SYSTEM ->
TEST -> CPU -> PRG. VER and then, press [1] key 5 times while pressing [SHIFT] key. The detailed version will appear.
Q18. Is the Main program commonly used for FM-8800D and FM-8800S?
See page. 5-8.
Yes it is. A change of the program is automatically carried out by detecting whether DUP RX board is installed or not.
Q19. I cannot update the program/How do I update the program? (Case 1) See page. 7-2.
If there is no problem with the PC setup or with the connection, there probably is a problem with RS-232C/RS-422 level converter. The speed in which the program is downloaded from PC to the Transceiver unit is 57.6 kbps.
Is the level converter speed even faster?
Q20. I cannot update the program/How do I update the program? (Case 2) See page. 7-6.
Am I supposed to select COM-1 for serial port?
If you want to use a serial port other than COM-1 then, you would have to update the batch file of the program that you want to update or select COM-1 for serial port on PC.
Q21. Remote Handset is not working properly. See page. 4-4, 5-23.
Each Remote Handset has to be assigned different ID number.
Have you set up different ID number? The factory setting is “1”.
Communication between Remote Handsets and Transceiver unit is made possible on the basis of this ID number. A communication between Remote Handsets with the same ID cannot be carried out.
Q22. I cannot receive DSC signals although telephone is working just fine.
See page. 8-8.
There may be a problem with a CH70 WR antenna or CH70 RX board.
1) Carry out a self-test. If the result is OK, electrical connection between CH70 Rx board and CPU board is OK then CPU board is fine.
2) Try exchanging CH70 WR antenna with RT antenna and then check it again.
3) Carry out [MENU] -> SYSTEM TEST -> T/A.
This test receives RX signal on CH70 RX board, modulates it on CPU board, and then outputs it to Handset ear-speaker and the speaker of the Transceiver unit as AFSK signal. If you cannot hear a DSC signal or noise, the, there may be a problem with CH70 RX board.
Chapter 9. Q & A
Q23. What are the differences between 05P0774A and B on TX/RX PCB?
See page. 8-19.
The 05P0774A is used for FM-8800S and the 05P0774B is used for FM-8800D.
The only difference is whether the input/output connector circuit is connected to DUPLEXER or not.
Q24. What is a DISTRESS MODE? See page. 1-6.
It just means that you have transmitted DISTRESS ALERT which removes a telephone priority normally set up in order of the Transceiver unit -> Remote 1 -> Remote 2 -> Remote3 -> Remote 4. In this case, communication can only be carried out from wherever PTT is pressed.
Q25. How can I clear memory? See page. 8-18.
You can carry that out by selecting [MENU] -> SYSTEM -> EEROM -> ALL.
Then, a pop-up window with “Init EEPROM” in it will appear and when it disappears, it means MEMORY CLEAR was done but it takes about 5 minutes.
Keep in mind this will clear all of LOG and setups as well.
Q26. When I make All Ship Call from No.1 VHF, I could not receive signals through No.2 VHF. Is the equipment broken? See page. 8-6.
It is not broken. They are made in a way that a call-up with the same MMSI dose not accept. For example, if you transmitted ALL SHIP CALL from No.1 VHF to No.2 VHF and incoming alarm and messages were outputted with the same MMSI, that would be very confusing as to who is outputting what. In order to avoid this situation, except when the Call Type is Individual and Category is Routine, reception of signals with MMSI will not be accepted.
Q27. Communication does not seem to be working correctly when Remote Handsets are connected. See page. 4-4, 5-23.
Have you set up different ID number for each Remote Handset? When more than one Remote Handset with the same ID number are connected, it causes a collision of data between the Transceiver unit and a Remote Handset. The ID number of factory setting is “1”. In order to set up ID number, unplug Remote Handset from RB-8800/8810 and then plug it back in while pressing [MENU]
key that is on it.
Q28. When I turn on the power, alarm keeps going off and nothing comes
up on the display. See page. 8-5.
That means CPU on CPU board is fault. You would have to replace CPU board then. This is a problem seen when CPU does not respond to a command from DSP.
Chapter 9. Q & A
Q29. Would disconnecting or short-circuiting antenna break Transceiver unit? See page. 5-14.
Transceiver unit: PA, No problem.
When R-VSWR was detected to be over designated voltage, FM-8800S/D automatically reduces PA output to keep it within its designated output.
Q30. “DSC-5” indication appears after a self-test with DMC-5. Is this okay?
DMC-5 displays DSC-5 when FM-8800 does not respond to CAID command from DMC during a self-test.
Note; In Russian Ver, DMC-5 is not connectable.
Q31. Please tell me about where to install the antennas. See Q37.
In order to avoid interference of signals, it would be advisable to install No.1 VHF antenna and No.1 CH70 WR antenna in Radar mast’s yard, No.2 VHF antenna and No.2 CH70 WR antenna in Compass deck.
Q32. What is the min. horizontal length between VHF Antennas? See Q37.
If possible, install then 10 m apart from each other but make sure keep they are at least 5 m apart.
Q33. Please tell me about where to install the VHF.
Install No.1 VHF on the starboard side and run a wire for both Wing MIC from there. Also, it would be advisable to install a Remote Handset where you operate a Radar.
Q34. Does a VHF Rack-consol have a type?
Yes it does. A VHF Rack consol type is called RC-8800 that consists of the main unit, printer (PP-8800), IF-8800, a handset and a hanger. Its three dimensional size is 330 (width) x 500 ( length) x 190 ( depth ).
Q35. Please tell me about RS-485.
RS-485 is one of the serial communication specifications standardized by EIA (Electronic Industries Association) and is of a higher standard than that of RS-422. RS-485 has a higher compatibility as well. While RS-232C is only allowed for one-on-one standardized connection and RS-422 is for one-on-several (multi-drop connection) connection, RS-485 is compatible with a bus-shaped multi-point connection and allows for the maximum of 32 connections. The rest of RS-485 specifications are based upon RS-422 and the maximum cable length is 1.2 km and the maximum communication speed is 10 Mbps.
Chapter 9. Q & A
Q36. Please tell me about communication range?
Below graph is to help you figure out the electric field intensity within a range of h1(10 m) and h2(the height of the other ship) when the signal is transmitted with 144 MHz and 10 W.
How to figure that out is:
For example, let’s say that if the height of the antenna on your own ship is 10 m high and other’s within 10~30 m, the point where the X-axis of the line with the minimum electric field intensity of +6 dB and the height of the other ship’s antenna, let’s say 20 m high for example, intersects is the RX distance in question here. However, make sure to shift the curve upward by 3 dB.
Therefore, we can confirm from below graph that 50~70 km (26~38 NM) is the VHF’s communication range and signals outside of it will be considered to be abnormally propagated signals.
+6 dB
e.g. Other ship’s antenna is 20 m.
